Windows XP/Vista/7/8

it might take some time being a freeware driver solution
Note: it will find all of your outdated drivers

This will automatically search for and find the correct driver you will have to update every driver individually once you update you might be asked whether you want to restart or make a system restore point.

Click no to both of these then continue updating each driver free then restart once all of the drivers have been updated.

on the home page you should see a search tab just type in what you are looking for

IE: Motherboard name sound drivers.

Place a tick in either windows software or all software box.

You might have to try a few times to get it right.

Installing only audio drivers will give you error "DRIVER INSTALLATION FAILED. COULD NOT FIND MEDIA DEVICE FOR THIS DRIVER" .so to solve this problem first you have to download microsoft universal audio driver and then install audio drivers
